In this study, the authors used Web-based surveys to examine differences in alcohol use by sex and ethnicity and factors associated with these group differences among 2,241 college-bound students. A Sex x Ethnicity interaction indicated that the sex gap was much larger for Latino than for Caucasian students. Although peer influence was important for both Caucasian and Latino students, family influences were significant only for Latino youths. The sex differences in drinking among Latino youths were largely explained by the combination of same-sex family member and same-sex peer drinking through values about the acceptability of drinking behavior. Among Caucasians, perceptions of peer behavior exerted a stronger influence on drinking behavior than among Latinos. These results suggest that interventions targeting peer influence are likely to be most effective for Caucasian students. In contrast, for Latinos, particularly Latina women, family characteristics may be an important target for prevention.  相似文献

Under-recognition of somatic symptoms associated with panic in primary care settings results in unnecessary and costly diagnostic procedures and inappropriate referrals to cardiologists, gastroenterologists, and neurologists. In the current study specialists’ knowledge regarding the nature and treatment of panic were examined. One-hundred and fourteen specialists completed a questionnaire assessing their knowledge about panic attacks, including their perceptions of psychologists’ role in treating panic. Respondents answered 51% of knowledge items correctly. Although most knew the definition of a panic attack, they knew less about clinical features of panic and its treatment. Specifically, whereas 97.4% believed medication effectively relieves panic symptoms, only 32.5% knew that cognitive-behavioral therapy (CBT) is a first-line treatment. Only 6% reported knowing how to implement CBT, and only 56.1% recognized that psychologists could effectively treat panic. These findings demonstrate significant gaps in specialists’ knowledge about panic and the need to enhance physician knowledge about panic attacks and their treatment.  相似文献

Evaluated the impact that actions of significant others have on adjustment following rape. Significant other behavior is conceptualized as having two dimensions--supportive behavior and unsupportive behavior--and each dimension was measured using multiple items. Unsupportive behavior, but not supportive behavior, was found to bear a significant association to victim adjustment. Implications for those who work with victims are discussed.  相似文献

A semantic categorization task was used to assess the structure of lexical knowledge in anterior and posterior aphasics. In general responses were faster for typical category members than for atypical ones and slower for semantically related nonmembers than for unrelated ones. Both groups performed at a high level of accuracy when classifying typical category members and semantically unrelated nonmembers. Their performance diverged at the category boundary. Anterior aphasics maintained relatively high levels of accuracy when classifying atypical category members and semantically related nonmembers while posterior aphasics did not. These results point to differences in the status of lexical knowledge for anterior and posterior aphasics.  相似文献

This paper views lexical acquisition as a problem of induction: Children must figure out the meaning of a given term, given the large number of possible meanings any term could have. If children had to consider, evaluate, and rule out an unlimited number of hypotheses about each word in order to figure out its meaning, learning word meanings would be hopeless. Children must, therefore, be limited in the kinds of hypotheses they consider as possible word meanings. This paper considers three possible constraints on word meanings: (1) The whole object assumption which leads children to interpret novel terms as labels for objects—not parts, substances, or other properties of objects: (2) The taxonomic assumption which leads children to consider labels as referring to objects of like kind, rather than to objects that are thematically related: and (3) The mutual exclusivity assumption which leads children to expect each object to have only one label. Some of the evidence for these constraints is reviewed.  相似文献

This study was designed to examine personal, stimulus, and organizational factors that predict the self-labeling of sexual harassment. Hypotheses were developed based on the social cognitive schema framework, which suggests that the activation of a victim's schema of sexual harassment influences self-labeling incidents as sexual harassment. Results of a secondary analysis of the 1995 Department of Defense Gender Issues dataset generally supported the hypotheses in that self-labeling is a multi-faceted process. Several findings were in the opposite direction from that predicted (e.g., perceptions that the military was implementing sexual harassment policies were negatively associated with self-labeling). Alternative explanations for the complexity of the self-labeling process were also examined. Portions of this article were presented as a poster at the 2000 Association for Women in Psychology conference in Salt Lake City, Utah. Authorship is listed alphabetically, both authors contributed equally to this study.  相似文献

Ecological contributions to attachment transmission were studied in a sample of 64 adolescent mother-infant dyads. Maternal sensitivity was assessed when infants were 6 and 10 months old, and infant security was assessed at 15 and 18 months. Maternal attachment state of mind was measured with the Adult Attachment Interview (AAI) after the 1st assessment. Ecological variables considered were maternal education and depression, paternal support, and infant maternal grandmother support. Results indicated that when the contribution of ecological variables was statistically controlled for, sensitivity was a significant mediator and state of mind no longer contributed to infant security. Sensitivity also mediated an association between maternal education and infant attachment, suggesting that attachment transmission is embedded in a more global process of infant attachment development.  相似文献

This study evaluated the anxiety sensitivity taxon using the 16-item Anxiety Sensitivity Index in relation to 2 criteria relevant to post-traumatic stress disorder; post-traumatic stress disorder symptom severity as indexed by the Post-Traumatic Diagnostic Scale, and post-traumatic cognitions as indexed by the Post-Traumatic Cognitions Inventory. Taxometric analyses of data collected from 331 young adults indicated that the latent structure of anxiety sensitivity was taxonic with an estimated base-rate range of 11-12%. As predicted, an 8-item Anxiety Sensitivity Index Taxon Scale accounted for significant variance above and beyond that accounted for by negative affectivity and the full-scale Anxiety Sensitivity Index total score in terms of both criteria. Moreover, after accounting for variance explained by the full-scale Anxiety Sensitivity Index total score and negative affectivity, the sum score for the 8 Anxiety Sensitivity Index items not included in the Anxiety Sensitivity Index Taxon Scale was associated with significant variance in these same dependent measures, but the relation was in the opposite direction to that predicted by theory. These findings are discussed in terms of theoretical and clinical implications for the study of anxiety sensitivity and post-traumatic stress disorder vulnerability.  相似文献

Myriad Genetics holds a patent on testing for the hereditary breast and ovarian cancer genes, BRCA1 and BRCA2, and therefore has a forced monopoly on this critical genetic test. Myriad launched a Direct-to-Consumer (DTC) marketing campaign in the Northeast United States in September 2007 and plans to expand that campaign to Florida and Texas in 2008. The ethics of Myriad's patent, forced monopoly and DTC campaign will be reviewed, as well as the impact of this situation on patient access and care, physician liability, and the future of DTC campaigns for genetic testing.  相似文献
